Re: these coals..
Trust me, the wait may seem long at first. But once you start smoking, its worthwhile ^_^
Just like Kevin said, just prepare your hookah while the coals are warming up so it won't seem as long.
BTW, after a while, warming up the coals won't seem so long. I've been smoking with naturals for months now and they don't seem like they take too long to warm up since I'm so used to them.
